Oligomeric silsesquioxanes, their preparation and their use in the synthesis of not fully condensed silsesquioxanes, of catalysts and their precursors as well as of polymers

New cyclic oligomeric silsesquioxanes have 6 substituent groups selected from alkyl, cycloalkyl other than cyclohexyl, alkenyl, cycloalkenyl, alkynyl, cycloalkynyl, aryl and/or heteroaryl. Oligomeric silsesquioxanes of formula R 6Si 6O 9and structure (I) are new. [Image] R : alkyl, cycloalkyl other...

Zusammenfassung:	New cyclic oligomeric silsesquioxanes have 6 substituent groups selected from alkyl, cycloalkyl other than cyclohexyl, alkenyl, cycloalkenyl, alkynyl, cycloalkynyl, aryl and/or heteroaryl. Oligomeric silsesquioxanes of formula R 6Si 6O 9and structure (I) are new. [Image] R : alkyl, cycloalkyl other than cyclohexyl, alkenyl, cycloalkenyl, alkynyl, cycloalkynyl, aryl and/or heteroaryl. An independent claim is also included for a method for the preparation of (I).
